The work is devoted to studying the influence of intumescence systems on characteristics of fire danger and operational properties of poliefiruretan coverings of artificial leather. The solution of poliefiruretan, intumescence additives, such as pentaerytol, ammonium polyphosphate, polyphosphate of sodium, titanium dioxide, aluminium hydroxide and melamine are used. It was of interest to determine the composition and quantity of input systems for the best results. The above additives were introduced in various ratios and quantities into the solution of poliefiruretan. For the analysis of the structure and properties of the received modified poliefiruretan films traditional methods of research were used. Thermal characteristics of films were investigated by the method of the thermogravimetric analysis, determination of thermal stability, combustibility on an ignition and spontaneous ignition method. Physicomechanica characteriatics of films and indicators of hygroscopicity of samples were also defined. As a result of the carried-out researches the
influence of the quantity and type of intumescence systems on the studied characteristics fire safety materials is shown and some recommendations about their use are made.
